SHIFT transformation function

Syntax

SHIFT (transformation BY x_shift, y_shift, z_shift)

Function

Return a transformation value resulting from shifting the position of the transformation parameter by the given shift amounts.

Parameters

transformation Transformation expression that is to be shifted.
x_shift Optional real-valued expressions that are added to the respective position components of the transformation parameter.
y_shift
z_shift

Details

The value returned is equal to the value of the input transformation parameter value except that the three shift parameter values are added to the X, Y, and Z position components. If any shift parameter is omitted, its value is assumed to be zero.

Example

If the transformation x has the value: 

(200, 150, 100, 10, 20, 30)

then executing the instruction: 

SET y = SHIFT(x BY 5,-5,10)

results in the transformation y receiving the value: 

(205, 145, 110, 10, 20, 30)
